GENERAL DESCRIPTION

The ADP3301 is a member of the ADP330x family of precision

low dropout anyCAP™* voltage regulators. The ADP3301

stands out from the conventional LDOs with a novel architec-

ture, an enhanced process and a new package. Its patented

design includes a noninverting wideband driver and a stage that

permits the use of an internal “pole splitting” capacitor to

stabilize the feedback loop with a single output capacitor as

small as 0.47 F. This device is stable with any type of capacitor

regardless of its ESR (Equivalent Serial Resistance) value,

including ceramic types (MLCC) for space restricted applica-

tions. The ADP3301 achieves exceptional accuracy of 0.8% at

room temperature and 1.4% overall accuracy over tempera-

ture, line and load regulations. The dropout voltage of the

ADP3301 is only 100 mV (typical) at 100 mA.

In addition to the new architecture and process, ADI’s new

proprietary thermally enhanced package (Thermal Coastline)

can handle 1 W of power dissipation without external heat sink

or large copper surface on the PC board. This keeps PC board

real estate to a minimum and makes the ADP3301 very

attractive for use in portable equipment.

100 mA Low Dropout Linear Regulator

The ADP3301 operates with a wide input voltage range from

3 V to 12 V and delivers a load current in excess of 100 mA. It

features an error flag that signals when the device is about to

lose regulation or when the short circuit or thermal overload

protection is activated. Other features include shutdown and

optional noise reduction capabilities. The ADP330x anyCAP™*

LDO family offers a wide range of output voltages and output

current levels from 50 mA to 300 mA:
